The aim of the current research is to identify the effectiveness of the learning department strategy supported by technical enrichment activities in developing the concepts of obligatory science and mathematical thinking skills among students of Sharia and law at Al-Azhar University. The research reached a number of results, the most important of which are: 1) There are statistically significant differences between the mean scores of the experimental group students in the pre and post applications for testing the concepts of obligatory science in favor of the post application. 2) There are statistically significant differences between the mean scores of the students of the experimental group and the control group in testing the concepts of post-mortem science in favor of the experimental group. 3) There are statistically significant differences between the mean scores of the experimental group students in the pre and post applications for testing mathematical thinking skills in favor of the post application. 4) There are statistically significant differences between the mean scores of the experimental group and the control group in the post-mathematical thinking skills test in favor of the experimental group. Research method and its variables and the experimental design used: The research relied on the experimental method; In order to identify the effectiveness of the independent variable (the learning circle strategy supported by technical enrichment activities) on the variables affiliated with the research, which are (exams of concepts of obligatory science, and mathematical thinking skills). As for the experimental design of the research, the researcher adopted the design of the two experimental groups, which numbered (50 female students), and the control group (50 female students), with both pre and post applications.
